If the kernel is compiled with CONFIG_CGROUP_BPF not enabled, it is not

to use IR decoding without cgroups or CONFIG_CGROUP_BPF enabled.
This change requires some refactoring, since bpf_prog_{attach,detach,query}
functions are now always compiled, but their code paths for cgroups need
moving out. Rather than a #ifdef CONFIG_CGROUP_BPF in kernel/bpf/syscall.c,
moving them to kernel/bpf/cgroup.c and kernel/bpf/sockmap.c does not
require #ifdefs since that is already conditionally compiled.
